Am I the only one who sees some similarity between Levi from AoT and Roxas?

[Nukara]

This inspired me after watching Attack on titan. I'm not saying that these two are copies of each other, since they grew up in different conditions and Levi is much older than Roxas. And yet, I see similarities between the two. They're both short. Quite straightforward. Stubborn. Plus they have a snarky trait (especially Levi's). In addition, in their universes, they are one of the most epic cool boy.
(I mean in KH3, Roxas can reduce the enemy's standard of living to a minimum, without any Sora intervention. And Roxas fans have a reputation for being a tough guy, pathetically knocking everyone right and left). I think these two could find a couple of common topics for conversation.
